It is the intake for deoxygenated blood, via the superior and inferior vena cava (huge veins), from all of the body other than the lungs. It pumps into the the right ventricle, which in turn pumps the blood via the pulmonary artery (the only artery without O2) to the lungs to get reoxygenated.
The function of the left atrium is to pass oxygenated blood from the pulmonary veins into the left ventricle.
The function of the atrium is to force the last bit of blood into the main pumping chamber (ventricle) before the power stroke to increase the efficiency of pumping.
The function of the left atrium is to receive blood from the right and left pulmonary veins and conduct that blood into the left ventricle.
The function of the left atrium is to pass oxygenated blood from the pulmonary veins into the left ventricle... i think?? that's my answer :)
It receives oxygenated blood from the pulmonary veins, and pumps it into the left ventricle, via the mitral valve. Atria facilitate circulation primarily by allowing uninterrupted venous flow to the heart, preventing the inertia of interrupted venous flow that would otherwise occur at each ventricular systole
The heart is made of four chambers. The top is the atrium, divided into two parts (left and right). The bottom are the ventricles, also divided into two parts (left and right).
So, the left atrium would be the left top compartment of the heart.
The oxygenated blood that came from the lungs enters the left atrium. After the systole of the left atrium the blood flows into the left ventricle, and from there into the aorta and throughout the body.
So, their role is to supply the body with oxygenated blood.
The left atrium and ventricle are sometimes called "the left heart", and the right atrium and ventricle "the right heart".
The right heart pushes the blood into the lungs circulatory system where the blood is being oxygenated, after which the blood goes to the left atrium etc.
It fills the left Ventricle with oxygenated blood
the purpose of the right atrium of the heart is to pull the none oxiginated (or blue) blood into the heart and pump it into the right ventrical
The left atrium is the upper chamber of the left side of the heart. It receives blood from the pulmonary vein and pumps it into the left ventricle.
carrys blood
Pumps blood into the left ventricle
the size of the right atrium is smaller that the left atrium.
Right Atrium , Left Atrium , Right Ventricle , Left Ventricle
The four chambers are; Left atrium Right atrium Left Ventricle Right Ventricle The two upper chambers are called atria (singular: atrium) and the two lower chambers are called ventricles. There are four chambers of the heart - the right atrium, left atrium, right ventricle and left ventricle.
As veins flow TOWARDS the heart, the PULMONARY VEINS are the only veins that carry oxygenated blood from the lungs to the LEFT ATRIUM.
4 chambers, the Left and right Atrium which are on the top and the left and right ventricals which are on the bottom
the size of the right atrium is smaller that the left atrium.
The left atrium empties into the left ventricle. The left atrium and left ventricle are separated by the left AV valve, or mitral valve.

the left atrium
the left atrium...it pumps blood thereThe pulmonary vein carries oxygenated blood from the lungs to the left atrium of the heart.
The two upper chambers are called the atria. A single atria is an atrium.
The four chambers are; Left atrium Right atrium Left Ventricle Right Ventricle The two upper chambers are called atria (singular: atrium) and the two lower chambers are called ventricles. There are four chambers of the heart - the right atrium, left atrium, right ventricle and left ventricle.
The left atrium carries oxygenated blood.
well you have two atria the right atrium and left atrium but i think the right atrium has deoxygenated blood and the left atrium has oxygenated blood.
As veins flow TOWARDS the heart, the PULMONARY VEINS are the only veins that carry oxygenated blood from the lungs to the LEFT ATRIUM.
4 chambers, the Left and right Atrium which are on the top and the left and right ventricals which are on the bottom
The 4 chambers of the heart are: 1.Left atrium 2.Left ventricle 3.Right atrium 4.Right ventricle
